`fixedEffect.Rd`

Specifies the initial values, lower bounds, upper bounds, and units for fixed effects in a model

## Usage

```
fixedEffect(
.Object,
effect,
value = NULL,
lowerBound = NULL,
upperBound = NULL,
isFrozen = NULL,
unit = NULL
)
```

## Arguments

- .Object
Model object in which to define fixed effects values

- effect
Character or character vector specifying names of fixed effects

- value
Numeric or numeric vector specifying the initial values of fixed effects. If supplying vector, must be in the same order/length as corresponding

`effect`

.- lowerBound
Numeric or numeric vector specifying the lower limit values of fixed effects. If supplying vector, must be in the same order as

`effect`

.- upperBound
Numeric or numeric vector specifying the upper limit values of fixed effects. If supplying vector, must be in the same order as

`effect`

.- isFrozen
Logical or logical vector. Set to

`TRUE`

to freeze the fixed effect to the specified initial value. If supplying vector, must be in the same order as`effect`

.- unit
Character or character vector specifying units of measurement for the fixed effects. If supplying a vector, must be in the same order as

`effect`
